Will Low Lamp Lifetime Spell Trouble for DLP TVs? 133

Posted by Cliff from the high-maintenance-television dept.
Techno-Canuck asks: "Now that the DLP TVs have been in customers' hands for the last few years, there are problem histories that are begining to unfold. According to Toshiba's DLP TV User Manual: 'The average useful service life for the lamp is approximately 8,000 hours in LOW POWER or 6,000 hours in HI BRIGHT MODE.' However there were problems with certain 2005 Toshiba models that saw the lamp lifetime at only a few hundred hours or less. Toshiba replaced the lamps in these models at no cost and extended the lamp warranty to 2 years. According to an FAQ on About.com the lamps currently last an average of 1500 hours. Whether or not Toshiba has resolved the problem remains to be seen, as only time will give the real indication. There also seems to be lamp issues with some 2004 models as well, but Toshiba does not seem to be stepping forward to resolve the issues in this case. The customer ire is starting to rise, however. Will there be similar problems for the 2006 models once enough time has elapsed?"
Most people probably would use the information provided by Toshiba to make a decision about what the lamp maintenance costs would be for DLP ownership. However if lamps only last for 1500 hours, then that's a 400% increase in costs over what Toshiba is presenting to customers. The cost of a lamp is $200 or more, and for a family household that averages 6 to 8 hours of TV viewing per day, this translates to a new lamp every 187 to 250 days. Strangely enough the Toshiba warranty on a replacement lamp not covered by the original TV warranty is 180 days.

It's possible that the death blow has already been struck. It appears that no longer carries DLP TVs in its product line."

    Problems like these will kill any technology in the cradle unless it has absolutely no competitors. If the 2006 models turn out to be anywhere near as bad, the game's already over.

      A tosh DLP that is. It sees very heavy usage in our household, and the lamp has been going for about 2 years now. It will probably die soon, the bulb that is, but hey, I knew bulbs were going to be consumables when I bought it. Most people that run short bulblives forget to switch on the "quick restart" feature that keeps the bulb on for about 10 minutes after you switch off the telly, and its the frequent on/off cycles that do more damage to the bulb then anything else.

I would suspect that it has to do with the 5 minute cool-down that the tv goes through every time you shut it off. You have no choice.

They did have temperature sensing but it was not enough to stop the shortening of bulb life. They did not have an airflow sensor but did have a tachometer in the fan which did nothing to measure airflow.

    They did well with the special power supply for them, it was intended to preserve bulb life and uniformity.

  • 46' Samsung DLP (Score:3, Interesting)

    We have a 46' Samsung DLP that we've had for almost two years now. The kids watch Nickelodeon, Disney, and Cartoon Network about 8 hours a day, then I or my wife (mostly my wife) watches maybe 2 hours a day. So far we haven't had an issue. The TV is great. When we bought it, the guy said get the extended (to 3 years) warranty at $150US. He said that the bulb last about 2 years under heavy use and that it cost about $150 to change and was covered under the warranty. That way if something did happen to the TV within three years it would be fix for the price of replacing the first bulb.

    The best thing about DLP TVs is that they don't get burn-in video games or other images left on the screen for to long like other types of TVs (tube, plasma, LCD or other types of projection TVs) It's the main reason we choose DLP in the first place.

        Don't know his situation, but, what if you live downtown Regina. Even if you find parks, the temperature in winter is usually in the -10C or thereabouts. Anyhow, _I_ can't imagine allowing my kids to watch that much TV, but, being single I don't have to worry about that for a while.

          You *must* be joking. :) I've lived nearly my whole life in Edmonton, and we used to build snow forts and go tobogganing when it was in the -20s.

    These bulbs are designed to fail... They could put 2 or 3 lower wattage/heat producing bulbs in these machines. More bulbs with less wattage would last much longer and could be much cheaper. They want the repeat business of selling bulbs, just like HP sells $50 printers that have $35 cartridges. Like printers though, changing bulbs will become an accepted norm, for DLP enthusiest. Hell, I don't mind, If I can afford the TV I should be able to afford the bulbs.. It's like buying a car and complaining that
  • LEDs are going to replace the bulbs and color wheels, greatly increasing light source longetivity and also eliminating rainbow effect. This may take awhile to trickle down from the high end devices. On the other hand, since the mfgrs won't want to lose customers over the bulb issue, they will have incentive to make the change ASAP.

  • But I have yet to see DLP that has a really good picture, and I'm talking with HD feeds. A friend of mine has a DLP (that needed a lamp replacement almost out of the box), and the HD quality is greatly inferior to my HD CRT, and we have the same feed. Similarly, I was looking at an HD display in the store the other day, with an High Def movie (not sure if it was Blu-Ray or HD-DVD) playing on the 3 major types (LCD, Plasma and DLP), the DLP looked like an analog signal being stretched to WS on an HD screen

    • Plasma is a pile of shit with design limitations. They STILL have burn-in and probably always will. The solution is to burn in the whole display and reduce your contrast ratio. Anyone who both plays video games and buys plasma deserves what they get.

      LCD, too, will be knocked completely out of the running by OLED when that finally gets cheap. I think OLED has the most promise. It doesn't matter much if the lifetime is short if they can get the cost down far enough, because they can just sell you a new sc

        Oh, I don't disagree with you. There's a reason I went with the biggest CRT I could find for my widescreen HD. I avoid plasma at all costs and warn off anybody looking to buy one.

        LCD is the best available at the moment in terms of size AND quality (but not value). I too am waiting for OLED to become practical, or even SED if it can ever get off the ground.

        My point is that in terms of pure image quality, I have yet to see a DLP that stacks up to the other options out there. If "good-enough" is what peopl
  • According to a random page I found while googling and not caring if it's valid or not, DLP recently has been in the lead among business projectors vs. LCD. See a few paragraphs down [studiodaily.com]

    That means the technology will stick around for a while, and I personally prefer the visual quality and price/performance of DLP vs. LCD and plasma. I don't think this bulb life "setback" will kill it since it doesn't have all its baskets in one egg :), eg. TVs.

  • My 51 inch RCA Scenium DLP is going on 3 years old now, and I'm still using the same bulb. The TV is probably on around 6 hours a day (whether we are actively watching TV/playing video games or it's just on as passive background noise) and in my opinion, it still looks as good as it did the day I bought it. The only negative thing I have to say about my TV is that it only goes up to 1080i since I was an early adopter.

    I have a Benq 6200 FP DLP with about 700 hours on it in two years now (I am not the earliest adopter...that goes to the Infocus X1 crowd). Paid $1150 for it. Best electronics investment I've ever made. Bulb life expectency 2000 hours at a cost of replacement near $400. That works out to twenty cents an hour or FORTY CENTS per average movie. I also use my projector for over the air HD (USDTV OTA tuner - Walmart) and DVD's. Mostly CSI and sports OTA. Bottom line: I was aware of the bulb cost and life expectency when I bought the unit. If you don't understand the technology and it's costs you should avoid. But let's look at the ALTERNATIVE of buying a 'smallish' 60" plasma. They gotta still be getting three grand for those??? I will be cashing out my social security before I buy enough replacement bulbs to get to THAT pricepoint and in the meantime I'm watching tv at a MINIMUM of 80 inches. OTA HD tuner: $200 FP DLP: $1150 (much cheaper now) Having your own home THEATER ----- PRICELESS. Enjoy.

      My CRT TV is from 1986. That CRT must have 20,000 hours on it. That works out to... 1-2 cent an hour or so, inflation adjusted. So there.

      Most CRTs easily last 15,000 hours these days.
